Suppose $\vec{u} = {\left<-6,1,-6\right>}$ and $\vec{v} = {\left<5,9,1\right>}$.

1. The second component of $\vec{u}$ is
2. $\vec{u} \cdot \vec{v} =$
3. $\vec{u} \times \vec{v} =$
4. $\left\| \vec{v} \right\| =$
5. Enter a unit vector in the direction of $\vec{v}$.
6. Enter a vector parallel to $\vec{v}$.
7. Enter a vector in the same direction as $\vec{v}$.
